Bug #725434 resulted in cairo-gl being disabled for causing "a 300% increase in memory use at login as compared to previously". Comment #12 mentioned a theory that this memory problem was actually in a version of libc nolonger used in Precise. I just tested the difference between memory use of some applications I expect to be using gtk+ at startup in Precise with and without cairo-gl enable. I installed cairo-gl via:
sudo add-apt-repository ppa:ricotz/staging sudo apt-get install libcairo2 libcairo-gobject2 While total real + swap = virtual memory is about the same, a number of applications do have roughly 300% of the memory usage with cairo-gl enabled as they do with it disabled. So it looks like we still have the cairo-gl + Nvidia proprietary driver memory problem? cairo-gl disabled enabled VIRT RES VIRT RES RES % compiz indicator-sound 517m 6868 649m 24m compiz 956m 120m 1043m 120m 100% nautilus 732m 28m 789m 45m 161% indicator-print 476m 9.9m 463m 28m 283% indicator-sessi 588m 6000 647m 24m indicator-print 476m 9.9m 463m 28m 283% indicator-messa 575m 6364 418m 23m indicator-appli 411m 4744 608m 22m indicator-datet 480m 7344 675m 25m ** Attachment added: "Same memory table above in plain text" https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/954352/+attachment/2893654/+files/cairo-gl.memory.txt -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gtk+3.0 in Ubuntu. https://bugs.launchpad.net/bugs/954352 Title: Enable wayland backend Status in “gtk+3.0” package in Ubuntu: Confirmed Bug description: Add --enable-wayland-backend to build flags. I believe this is all that's necessary for wayland to work with the existing Precise gtk packages. Wayland has one released version, 0.85, which is in the precise archives: https://launchpad.net/ubuntu/+source/wayland/ I'm told gtk 3.4 is (and will remain) compatable with it. Since gtk 3.4 is apparently already packaged for Precise, all that remains to be able to use some gtk applications via wayland is this build flag.
